Description

 Specification

 Binocular loupe

 Technical field

 [0001] The present invention relates to a binocular loupe used in medical surgery and precision work, and more particularly to an embedded binocular loupe in which a binocular loupe is attached to a spectacle portion of a spectacle frame.

 Background art

 [0002] A binocular loupe has been widely used in various fields such as the medical field, precision work, and jewelry processing as a means for enlarging and visually recognizing a local visual object at hand. In these fields, high accuracy is required for work and operation, and in the medical field in particular, it is related to human life, so the binocular loupe vision correction and astigmatism correction are precisely adapted to the visual acuity of the worker. It is required to be.

 [0003] In addition to the excellent resolving power, wide field diameter, deep focal length, etc., the binocular loupe is required to have a bright and clear image quality, and from the ease of handling, maintenance is required. For this reason, waterproofing that can be washed with water and corrosion prevention are necessary. Also, the magnification adjustment of the primary mirror loupe needs to be configured to be adjustable according to the application.

 Disclosure of the invention

 Problems to be solved by the invention

[0005] However, with such a conventional binocular loupe, the precision of the lens that corrects the visual acuity of the operator is determined by the operator even though high precision is required for the manual operation of the precision operator. Since it is difficult to appropriately adapt to the visual acuity at the time of the work, there is a problem that the visual accuracy is uneven due to the change in the visual acuity at the time of the worker's work. In other words, even though the human eyesight always changes depending on the physical condition and the degree of fatigue, and even on the same day, it changes between morning and afternoon, the conventional binocular loupe is able to change the visual acuity of the worker. Adapt As a result, it is necessary to work with a binocular loupe in an inappropriate state of vision. It was necessary to prepare a pair.

 [0006] The present invention has been made in view of the above-described problems of the conventional binocular loupe, and can appropriately correspond to the constantly changing visual acuity of a medical operator such as a doctor or an operator who performs precision work. It aims at providing a simple binocular loupe. It is another object of the present invention to provide a binocular loupe that can perform operations for adjusting visual acuity extremely easily.

 Means for solving the problem

In order to solve the above problems, a binocular loupe according to the present invention is a binocular loupe for enlarging and viewing an object at hand, including frame means, a pair of binocular loupe bodies, and the binocular loupe. Mounting means for fixing the main body to the frame means, focus adjusting means for adjusting the focal length of the binocular loupe main body, and support for attaching the focus adjusting means to the eyepiece portion of the binocular loupe main body detachably And a binocular loupe having the means.

 As described above, the binocular loupe according to the present invention can be attached to the eyepiece portion of the binocular loupe main body so that the focus adjusting means for correcting the visual acuity of the operator can be detachably attached. This makes it possible to appropriately correspond to the visual acuity to be performed.

 [0009] Here, the mounting means includes a primary mirror mounting frame, a primary mirror mounting carrier lens fixed by the primary mirror mounting frame, and the primary mirror mounting carrier lens. A primary mirror mounting portion fitted in the opening.

 [0010] Further, a plurality of types of the focal point adjusting means having different focal lengths are prepared in advance, and one of them is selected and attached to the supporting means.

 [0011] Since the focus adjusting means and the binocular loupe main body are each provided with either a convex portion or a concave portion for engaging each other, the binocular loupe main body of the focus adjusting means It is easy to attach to and detach from.

[0012] In addition, in the present binocular loupe, the focus adjusting means and the binocular loupe main body are engraved with alignment lines for engaging the two at a predetermined position. As a result, astigmatism can be corrected appropriately.

 [0013] By the way, each of the two joint surfaces that join the focus adjusting means and the binocular loupe body to each other is provided with either a magnet plate or an iron plate for engaging the two with each other, The focus adjustment means can be very easily attached to and detached from the binocular loupe body. In this case as well, each of the joint surfaces of the focus adjusting means and the binocular loupe main body is provided with either a convex portion or a concave portion for engaging the two at a predetermined position, so that an appropriate position can be obtained. Enables matching.

 [0014] Each of the two joint surfaces that join the focus adjusting means and the binocular loupe main body to each other is provided with a flange for enlarging the area of each joint surface. Each of the plate and the iron plate is disposed on the flange.

 The invention's effect

 [0015] As described above, according to the binocular loupe of the present invention, the detachable focus adjusting means capable of adjusting the focus of the binocular loupe main body is added to the eyepiece portion of the binocular loupe main body in an additional manner. Since it can be attached, it is possible to provide a binocular magnifying glass that can be appropriately adapted with a simple attachment operation to the current visual acuity during operations such as medical surgery and precision processing.

 [0016] Further, since the focus adjustment means can be appropriately selected from a plurality of focus adjustment means having different specifications, an appropriate one that matches the visual acuity at the time of work by a precision worker is appropriately selected. There is an effect that can be used. In addition, when the focus adjustment unit is attached to the binocular loupe body, it is configured so that it can be accurately aligned with the binocular loupe body. The optimal visual acuity could be secured by the alignment.
